To all tvftom it may rom'rrn:

Be it kuosu that I. 'ILLIAM J. Ems. a citizen of the United States, residing in (hicauo, in the county of (wk and State of Illinoie, have invented it new and useful I mproveiuent in w'tl ttbvttlt'lltg .\ltt t'ltlltt'a, of which the following is it qu t-titrat on.

This invention relates more particularly to the construction of wood carving machines adapted to carve simultaneously a plurality of separate but uniform pieces of uork, but certain features of the invention out have it broader utility and be applicable c scwlteru w Heretofore the tools have ent-rally been driven by belt im the moat avored menu for actuating them, but belts are subject. to many and serious objections, due largely to their stretehin' and the many changes in position to which the tools are subject, and

which are generally rcquirttd of them in the doing of a, aingle tern of work. The belts also are not capab of revelvi the cutters at as high a a as its deeira le. I have conceived that the belts mity be wholly diapenaed with, and the cuttera be driven at, a greatly in? pressed area the .power supplying agent. and provuhn each cutter till a separate actuating tur tint! or other suitable constructiol't of Winged wheel adapted to bit-rotated Iby'the compressed air. By this change I not only greatly simplify and improve the machine and enabl it to do umch more and better taork than has hitherto been possible, but I out also enabled to give the cutters on increased range or adjustment eiiablin them to do uork which could not be done Irv the machines Whose cutteis we're driven bv belts.

The carving tool and actuating mechanism hereinafter 'dcsci'ilwd mar be employed siti- ,gly as \t'tlltts in gang. The turbine rotating ceased speed by employing coini mechanism set. forth may be utilized otberwise than in actuating a nood earvin drill ood the rotary movement generator may 7 ,even be transformed into it reeiprocntimg movement for the actuation of a tool ilmt i in required to have a back and forth moveuncut with or without a factor of rotation.

In naid drawing, -lt repreaertta the corner and mums uniting the uprights and forminwith them the frame of the machine. Ihilteo' to the uprights 11 at each end of the machinare beams 13 forming ways upon which tl-i work table 14 may be supported and ltljttst ttl forward or back. table with tingle iron ruiincra l 0, and tin benms with strips-I30 upon which the runners bear. ()no of the strips is thicker lllul guide. The blocks 15 to be curved as well as the pattern l6 are secured to this table in any suitable war, as for instance by the bolt hoolui t7. "the table iii adapted to permit. the po.-;itioning of the hooks wherever necesearv Its will he understoodv from Fig. 4.

he gang of carving tools 18, as well as the pattern tracer it) are aupported from a,tube 10 which I call the header tube and-which is connected-by a flexible pipe 21 to a ti'iuk or reservoir charged with air under the desired degree of pressure or to an air compresmw and is arranged Iparallel to the work bed of the machine. mob of the carvers is. re vided with a head 22 fitting the outside 0 the i bender tube 20 and split as at 23 so it may be i made to clam i the tube by tightenin the 1 bolt 24. The leads are {'oiucd to chain red I castings-.25 by pivot ho ts 26, and the cast.- iugs '25 are threaded at their bottoms and engugc the tunings 27 of turbine wheels to be described Inter on. v In the heada 22 end Castings 25 are formed air passages 28 com I a horiyow; lttl ttt't'lltm on the lined-4 of Fig. t.

The w a eonaist ol huha til rims it: and vanea 33 arranged between the huh-t and the ritna and preferably of the eoneavo-eonrex form ahown. 'lhehuha are threaded on the upper ends of apindles tit, and the spindles have eollara 35 renting on the tops of tubular 3n threaded into the ring 37 formed at the ttom of tn converging arms as of the eaainga 27. At their lower ends the apindlea have enlargementa 30 in the slut ie of aplit eonea and carrying nuts to in wide l the earring toola are entered. Immediately over the wheels and clamped hetween the easing and the chambered eaatinga are llat air-diatribtlt platen 41 in which openings 42 are termed a pitch relation to the vanes oi the whaala a to admit air to the vanes. And lll order that the openings may direet the air so it will he etleet-tre upon the vanes, l ireler to form them by slitting the piates and Wildin the metal up at one aide ol .the slit and downward at the other side as seen at Fig. 10. The downward bend thus given the plate naeeaaitatea the notehing out of the vanes as aaeu at 390.

Thegointa between the heads 22 and east- 2 are aueh aa permit a rocking by the latter on the vote 26, to carry the tools in lateral directions, and in order that these movements rna he uniform in the case of the tracer and too a, I provide the rhamhered ealtinga and the tracer with upwardly extendi arma 43, and these arms are al pivotally oined at their tops to a horizontal har 44. e tracer holder is tnadu in two parts with the lower part 46 pivoted to the upper part the joint is ocated in the same lane an that. between the heads and t-htunlierod eaainga til the tool holders. 'l'he pivot. of the joint in aim at aerew 47 aml operated i 'ahand wheel 4H. By tightening screw 4?, tie parta of'the joint are brought togetlu-r and the rocltiup movements mentioned are prevented and iy haaiening it the parts are released and the movements permitted.

It will be noted that not only are the carving toola adapted to he ti pcd on their plvpts 2o, but that they are N opted to be carried back and forth and about the'right'or lcftto any extent needed. Also that the cqualizin device regulating the forward and lmckwsn movements of the header may be secured to the tront or rear uprights as desired, so that the header and tools mnv be reversed from the 'tiona ahown and ace the rear of the The use of a turbine of the character above indicated, toractuatin the tools, permita the maintenance of a mue higher a l of revolution than could be auccesafu ly imparted by pulleya or similar mcchantsm aml at the same time provides the moat direct tblo application of power to thc asid too and a more even and steady high speed movement than could be otherwise imparted to them.
